ROBERT D. BERG, OF .ST. PAUL, MINNESOTA.

TRACK-DRILL.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed September 24, 1912. Serial No. 722,030.

To all whom it may concern Be it known that 1, ROBERT D. BERG, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Track-Drills, of which the following is a specification.

My invention relates to power operated machines for drilling track rails and the object of the invention is to provide a machine adapted particularly where a large amount of drilling is required, as when new rails are laid or when anti-creepers are put on the track.

A further object is to provide a machine which can be easily and quickly moved from place to place on the track and by means of which holes can be accurately and quickly drilled in the rails.

A further object is to provide a machine which is adapted to run on the track but can be readily lifted ofi the rails whenever desired.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a plan view of a track drilling machine embodying my invention, Fig. 2 is a side elevation of the same, Fig. 3 is a front elevation of a portion of the machine, showing the manner of mounting the drills thereon, Fig. 4: is a detail view, showing the tilting drill carrier, Fig. 5 is a detail sectional view, showing the means for feeding the drill, Fig. 6 is a detail sectional view, showing the train of gears between the driving shaft and the drill spindle, and the means for supporting the drill carrier on the machine, Fig. 7 is a detail sectional view, showing the driving connection between the engine shaft and the drill carrier gears, Fig. 8 is a detail view showing the manner of mounting the drill carriers on their shaft.

In the drawings, 2 represents the track rails.

3 is a frame, preferably of cast metal, having bearings on axles 4; and 5 which are provided with carrying wheels 6 and 7 These wheels are adapted to rest and roll upon the track rails.

8 represents a gas engine, mounted on the frame 3 and having a shaft 9 running lengthwise of the machine and provided at its rear end with the usual fly wheel 10.

11 represents a water circulating system for the engine and 12 is a gasolene tank.

The forward end of the engine shaft projects in front of the machine frame and is provided with a worm 13 arranged within a suitable casing or housing 1 1. This worm meshes with a gear 15 that is mounted on a transverse shaft 16 which extends from side to side of the machine at right angles to the engine shaft. (See Fig. 1). The shaft 16 has bearings in brackets 17 provided on the forward portion of the machine frame. The forward portion of the machine frame preferably has upwardly turned portions thereon forming standards 18 whereto a transverse plate 19 is secured. This plate has beveled longitudinal edges and forms a guide for the carriages 20, which are adapted to slide back and forth thereon on each side of the machine for the purpose of moving the drills toward or from the work. Any suitable means may be employed for moving these carriages, but I prefer to provide screw shafts 21 mounted in bearings 22 on the plate 19 and engaging the threaded openings in the carriages 20, so that when the screw shafts are revolved by means of the cranks 23 the carriages will be moved transversely with respect to the machine. The carriages 20 have forwardly projecting lugs or ears 24: thereon. Drill carriers 25 have similar ears 26 adapted to slip in between the ears 2 1. Sleeves 27 are slidable on the shaft 16 and have threaded inner ends adapted to engage the interiorly threaded ears 2 1 and fit loosely within the ears 26 to allow the drill carriers to swing forwardly and upwardly, independently of the carriges, and also be capable of a transverse sliding movement on the shaft 16 when the screw shafts 21 are operated. Gear wheels 28 are mounted on the shafts 16 and through a train of gears 29 operate gears 30 on the drill spindles 31. These spindles are adapted to receive drills 32. These drills with the carriers are adapted to swing forwardly and upwardly and on the upper portion of the carriers I prefer to provide pivoted arms 33 having curved bearing faces 34 at one end which are adapted to contact with the forward axle 5 and hold the drill carriages in a raised, inoperative position, as indicated by full lines in Fig. 4:. When these arms are allowed to drop down to a vertical position the carriers will swing down and assume a substantially upright position, ready for the drilling operation.

For the the drill carriers with respect to the ground line, I prefer to provide adjusting screws mounted in the drill carriers and adapted to contact with the forward portion of themachine frame, so that the operator, by revolving these screws, can swing the carriers on their pivots and raise or lower the drills. I also prefer to provide levers 36 nmnnted on the drill carriers by means of which they can be easily and quickly tilted ontheir pivots. The drill spindles have a. splined connection with the gears 30 to slide freely therein and turn when the gears 30 are revolved. One end of the spindle is provided with a drill socket 37 to receive the end of the drill and at the other end of the spindle is a sleeve 38 secured on the spindle by' a lock nut 39 and provided with a rack 40 which meshes with apinion 41 secured on a shaft 42. A disk 43 is secured on said shaft and has a series of sockets ts therein to receive an operating lever 45. The rocking of this lever will move the spindle and feed the drill to the rail. The drills may be operated simultaneously or independently of one another, as desired, the adjustment toward and from the WOIC being easily and quickly performed by means of the screw shafts 21 and (he feed of the drills being accurately regu- .lated by the rack and pinion mechanism described. Both drill spindles will be operated simultaneously through the driving connection of the shaft 16 with the engine shaft, but either one of the drill carriers may be swung to an inoperative position or it may be set at a point where the drill will be out of contact with the rail, or if the work is to be performed mostly on one side of the car the drill on the other side can be entirely removed from its socket. In the operation of the machine, the end thrust of the drill will be taken up by the flanges of the carrying wheels.

For the purpose of sharpening the drills conveniently, I prefer to provide an emery wheel 46 mounted on a spindle .1.7 having a pulley 48 thereon that is belted to the fly wheel or to some moving part of the machine. The emery wheel is preferably provided at the rear portion of the car on a suit able bracket 49..

In the operation of the machine, the car is set at a point wherethe drilling is to be performed, the drill placed in its socket and the carriage lowered to the desired level. The carrier andv carriage being moved to their working position the engine is started and the drill fed into. the rail until the work is complete. When either drill carrier is not in use it may be swung up and supported in its raised, inoperative position.
